Bible Verses About Time: Indicated by a sundial

Yesha'yahu said, "Here is the sign for you from ADONAI that ADONAI will do what he said: do you want the shadow [of the sundial] to go forward ten intervals or backward ten intervals?

Hizkiyahu answered, "It's easy for the shadow to go down ten intervals. No, let the shadow return backward ten intervals."

Yesha'yahu called out to ADONAI, and he brought the shadow on the sundial of Achaz ten intervals backward after it had gone down that far.

that I will cause the shadow of the sundial, which has started going down on the sundial of Achaz, to go backward ten intervals.'" So the sun went back ten intervals of the distance it had already gone down.
